VIBCO produces 3” and 4” wide wedge brackets. The 3” models have been a standard in the industry for many years. The increased requirements for faster production and more powerful vibrators made it necessary to develop the stronger 4” wedge. Two pneumatic units with the wedge as a permanent part of the unit were developed - Model CCW-2000W and SVRWS-4000W. The CCW-2000 needs no lubrication and is absolutely quiet, 75-80 dB, ideal in places where noise is objectionable. Model SVRWS-4000 is a high frequency unit and will produce a strong and architectural finish to the concrete together with a fast pour. The SVRWS as well as the 42-2” piston type vibrator need continuous lubrication. Almost any vibrator can be adapted to the separate male bracket. The 115 volt models US-900 and US-1600 are the most popular ones. Their light weight and high frequency make them excellent units for obtaining high strength and architectural finish. For the smaller forms the 3” wedge is used with smaller vibrators such as the pneumatic turbine VS-line.

The lug type bracket has become more popular due to the fact that it secures the vibrator firmly and 95-100% of the vibration force is transmitted. There are two lug type brackets, the small LC-2 and the larger LC-1.
The SVR units with their high frequency and high force are used for the big jobs. They give a fast pour, high strength and an architectural surface finish. These pneumatic units operate at 9-12000 VPM and up to 100-110 PSI on lubricated air. These bearingless units have only one moving part and require a minimum of maintenance.
The CCL-2000, CCL-4000, CCL-5000 and CCL-7000 are turbine type vibrators with speeds up to 7000 VPM, absolutely quiet. Their bearings are prelubricated for life.
Model 2PL-900 and 2PL-1600 electrics are made in both single phase and three phase. USL-900 & USL-1600 are high frequency vibrators with 9000 to 10000 VPM. They are 115 volt and can be plugged into any light outlet or used with field generators. Speed can be adjusted with simple rheostats or electronic speed adjusters. Force is also adjustable with 3 force settings on the eccentrics.
Model HL- 3000 hydraulic is equipped with VIBCO’s patented vibration isolation device, which eliminates vibration transfer from the vibrator part to the drive motor giving the motor bearings their full calculated life.

The ones listed here are the most common. They will all give VIBRATORS satisfactory results but it is wise to recognize the advantages and limitations of each model. BS-160, -380, -570 Roller Vibrators Model BS with one moving part, a roller spinning free inside the housing. The preferred unit hand held or attached to small statuettes or the like forms, will make the stiffest mixes liquefy and flow, eliminating air entrapment. These units TURBINE need lubricated air. Air consumption quite a bit higher than the VIBRATORS turbines, speeds up to 11-12000 VPM, noise level 80-90 dB, force to 3000 lbs. Recommended pressure up to 80 PSI.
Turbine Models VS & BVS consist of a turbine wheel spinning on bearings attached to the shaft. The only ones not needing lubrication, they have the lowest dB reading 72-78 which is no more noise than an electric motor. They also have the lowest air CCF-2000, -5000 consumption. Speed on the smaller units 7-8000, on the larger ones 5-6000, force up to 5000 lbs., recommended pressure up to 80 PSI.
Model SVR’s VS & BVS the real workhorses of the pneumatic line. These vane roller units are bearingless with only two moving parts, a delrin vane and a rotor. They need a continuous lubricated air flow. These units are both the high force, up to 8000 lbs., and the high frequency units, up to 12000 VPM, preferred on the large concrete HIGH FREQUENCY job for fast pour of the stiffest mixes, fast consolidation for optimum VIBRATORS strength and architectural surface finish. Forces from 4000 to 8000 lbs. Frequencies from 9500 to 12000 VPM. Special units can be made for up to 16000 VPM. The most common ones are the lug type, see page 6 &7.
Two models available: SILENT and Conventional A. The conventional models with a dB reading of 95-100 are the low cost models. Due to the noise level of conventional models the silent versions may be a better choice. B. Silent Models, the SVRS line, have a dB reading of 80-85 SVRFS-4000 (within the OSHA limits). These patented units channel the air SVRFS-5500 throughout the unit in such a way it eliminates much of the noise created in the conventional units. Force and speed matches the SVR-4000 conventional units size for size. VIBCO’s patented SVR’s have some definite advantages over other makes, such as: • VIBCO’s “START EVERY TIME” HYDRAULIC • VIBCO’s patented air saver chamber saves air- other units VIBRATORS must exhaust all air before starting a cycle • VIBCO’s patented wear plates eliminate costly end cover wear which can create sluggish operation, excessive air consumption, and costly down time • VIBCO’s vibrators are made in the U.S.A.
HYDRAULIC MODELS The hydraulic model HF-3000 operates on pressures up to 1500 SVRS-5500 HF-3000 PSI and creates 3000 lbs. of force at 7000 VPM.

I. CHOOSE ELECTRIC OR PNEUMATIC VIBRATORS In the U.S., the most common vibrators are the pneumatic. They are easy to use, safer, lightweight, portable, simple to repair and cost less than electric. The smaller, electric 115-volt plug-ins are popular, especially on small forms and on outside jobs where a generator is easier to use than large air compressors and air hoses. Large 3 phase electric vibrators are primarily used on vibrating tables and large pipe forms where they are permanently mounted on the forms.
II. PORTABLE OR PERMANENTLY MOUNTED, WHICH TO CHOOSE? The permanently mounted vibrators will last longer “maintenance-wise”, transmit vibration better, and release an operator for other duties. The portable vibrators are very popular – one vibrator can be moved to different positions, used on different forms, and additional female brackets can be mounted in places where additional vibration is required. A host of different types of brackets are available from VIBCO to help with this type of application.
III. WHICH MODEL AND SIZE VIBRATOR TO CHOOSE? A. First determine how much vibration force is needed for the complete form. Add form weight to concrete weight with the following adjustments. It is important to know what slump concrete is used. a. For concrete with 0” slump or dry concrete, add 200% to the weight of form plus concrete to get the vibration force needed. b. For 1” to 2” slump, add 75% to form and concrete weight to get total force needed. c. For concrete with a 3” to 5” slump – standard for all over the road delivered concrete trucks – use vibrator force same as the form plus concrete weight. B. Placement of vibrators - Vibration force travels in a 3’ to 4’ radius from the vibrator on steel forms. It dissipates rapidly thereafter. Place vibrators in a pattern so that vibration forces overlap slightly. The corners are usually very stiff, so place vibrators close to the corners on a 2.5’ to 3’ radius. C. Penetration - Vibration force penetrates concrete up to 6” to 8” depending on slump. Concrete is thicker than 8”, vibrators (staggered) are needed on both sides of the form. D. How many vibrators are needed? Make a layout of your form and place vibrators on 6’ to 8’ centers (vibration travels a 3’ to 4’ radius). On corners, place vibrators on 5’ to 6’ center (2.5 to 3’ radius). Once you have laid out the vibrator pattern and you know how many you need, divide the numbers of vibrators into the total weight of form and concrete (see paragraph one). The sum is the VIBRATION FORCE needed on the vibrator. E. Which vibrator to choose? VIBCO has over 300 vibrator models, pneumatic, electric and hydraulic, to choose from. VIBCO has been in business since 1962 (over 40 years), and certain vibrators have proven to be the best solution, best value and require the least maintenance for concrete applications. Below is a list of the most commonly used vibrators:

The 115-volt “plug-in” electric models US and USL are popular for small to medium forms when compressed air is not always available or on job sites where generators can be used. The larger 3 phase models – 2P-800 and up – are used for permanent mounting on concrete pipe forms and vibrating tables. The pneumatic vibrators are by far the most popular ones, they are low cost, lightweight, easy to mount to any bracketry, and easily repairable by the mechanic on the job site. The pneumatic turbine lines VS, CCF, CCL and CCW are the most popular for the small to medium size forms, because of their noiseless operation, noise as low as 72dB at high frequency and light weight . They are pre-lubricated for life so no lubrication is necessary.
FOR THE LARGER FORMS The larger CCF, CCL-4000, -5000, and -7000 are used for larger forms. They are quiet, high force, and no lubrication is required. These units are also excellent for self-consolidating concrete. The SVR line of high frequency vibrators can produce as high as 15,000 VPM, which is ideal for obtaining a smooth architectural finish. The standard units have frequencies of 8,000 to 12,000 VPM for fast placement and producing strong, void-free finishes. These units must be continually lubricated to maintain their speed and force output. F. Vibration procedure and vibration time. 1. Vibration Procedure: Place vibrators to be used in their lowest position. It’s a good idea to pre-mark the vibrator position. Do not start vibrators until the concrete reaches them or is no more than 6” above them. TIP: If internal vibrators are used, do not start the external ones until the internals have stopped or moved to a higher position. The reason for this is, internal vibrators throw air bubbles away from the vibrator head against form side leaving air holes and pockets on the surface. External vibrators throw air bubbles into the mix, up and out, leaving surface against form smooth and blemish free. 2. How long to vibrate? Some experimentation on the customer’s part is always necessary because the time you need to vibrate varies depending on concrete slump, additives, stiffness of form, vibrator force, etc. Do not start the lowest vibrator until the concrete reaches them or is no more than 6” above. The concrete stiffens the form and if vibrated earlier, the vibration might move the form, making it flex, promoting leaks and seepage. a. If there is only one vibrator on the side of the form, keep it vibrating until the form is full and no more air bubbles are breaking on the top of the concrete and a glistening surface appears. b. If there are multiple vibrators per side, keep the lower vibrator running until the concrete pour reaches the higher vibrator – then stop the lower one, start the higher one and let it vibrate until the pour is complete and no more bubbles break on the surface of the concrete and a glistening surface appears. G. Helpful hints and corrections after you strip the form (please see page 27 under septic tanks). H. Additional Tips 1. Metal forms transmit vibration far more effectively than wood forms. 2. Always stiffen up forms to avoid distortion and flutter and for best vibration transmittal to concrete. 3. Rest forms on wood beams or rubber mats to avoid vibration transmittal to floor and surrounding forms, as well as for quiet operation and increased vibration amplitude and uniform compaction. 4. Vibration time depends on height and structure of form. Vibrators should be operated until a flat, glistening surface appears and no more air bubbles burst on the surface. 5. Concrete of proper consistency is not susceptible to over vibration and segregation. If segregating occurs, reduce slump, not vibration time and tighten form joint. Our experience has been to see “under-vibration” rather than “over-vibration” due to too short vibration time or force, to get a homogenous, air-bubble-free mix.

Easy 115 volt plug in, low amperage and can be plugged into any light outlet. US-900 is mounted on a wedge bracket model UW-2 (pages 2-5). The UWF female bracket is welded to the form (see mounting below). The US-1600 is mounted on a UW-3 wedge. The US-900 is used on standard septic tanks, US-1600 on larger ones.
IMPORTANT NOTE: High Frequency Electric Vibrators are intermittent duty units with a maximum “on” time per hour of 30 minutes. If vibration time extends beyond the duty time, use two units and leapfrog them from form to form.
The wedge brackets transfer vibration up to 90%. For 100% transfer use Model USL-900 & USL 1600 with lug bracket (see page 6 & 7). For Burial Vaults use Model USP-900 (page 9).
PORTABLE PNEUMATIC: For septic tanks use Model SVRWS-4000 Silent High Frequency Vibrator up to 11,000 VPM (page 3). This unit is recommended for the larger forms and CCW-2000 (page 3). Silent Pneumatic Vibrator is recommended for the smaller forms. CCW-2000 is prelubricated for life and the SVRWS-4000 needs to be lubricated from an oiler in the airline. For burial vaults use VSP-510 silent pneumatic turbine vibrator (see page 9).
PERMANENTLY MOUNTED VIBRATORS: Many concrete producers choose to mount the vibrator permanently on the forms to save time, lower labor cost, and reduce handling of the equipment and repair costs.
Suggested vibrators for permanent mountings are Electric Model US-900 for standard septic tanks and burial vaults. US-1600 in single phase or 2P-200 in 3 phase (page 16 & 17) or the pneumatic unit Model CCF-2000 for standard septic tanks and for the large ones Model SVRFS-4000 (page 14-15). For burial vaults use Model VSP-510 (page 9). HOW & WHERE TO MOUNT THE VIBRATORS
QUESTION: Why can’t I mount the vibrator to the skin of the form? ANSWER: When you put a vibrator directly on the skin of the form, you create several problems. 1. You create an “oil canning effect.” The movement of the skin actually draws air in, producing air holes. 2. The vibration energy is not distributed over form side but is concentrated just around the vibrator. This concentrated force will create fatigue cracks in the form skin and the vibration may actually tear out a piece of the form around the vibrator. The concentrated vibration energy also may cause segregation where the vibrator is mounted. The correct way to mount the vibrators is on a stiffener to distribute the vibration energy or force over a larger surface as well as to prevent the “oil canning effect,” reducing the problem of fatigue cracks.
SUGGESTION #1 SUGGESTION #2 Acceptable Mount: Preferred Mount: Mounting plate Channel iron over parallel to stiffener stiffeners
VIBRATOR
#2 preferred mount is better because: 1. An added stiffener is usually only tack welded to the skin of the form and if welds are not reinforced fatigue cracks may develop. 2. If you secure a channel iron over 3 stiffeners as in the preferred #2 mount, you are using stiffeners that are a rigid part of the form and the energy forces of the vibrator are used much more effectively.

TECHNICAL HINTS FOR VIBRATING SEPTIC TANKS AND BURIAL VAULTS Some experimentation on the customer’s part is always necessary because the end result is determined by the way the forms react to vibration transfer, the concrete mix, additives used, and the form oil. For casting septic tanks we recommend the use of two vibrators. Start the pour as usual, and if a continuous and quick pour is planned, begin to vibrate when concrete is 6” above vibrator. If vibration is ample you should notice a leveling off of concrete and glossy surface and air bubbles rising to the surface. Continue vibrating for about a minute after pour is completed. If placement of concrete is intermittent then vibrate for 1 to 2 minutes more after each pour. When the concrete has been thoroughly vibrated a glossy surface and few (if any) air bubbles bursting on the surface will appear. TROUBLESHOOTING AND CORRECTIONS AFTER YOU STRIP FORM. 1. Separation of aggregate (too long vibration time or too much water in mix). 2. Bleeding of cement and water (tighten seals in form or use less water). 3. Honeycomb (often from bleeding, but if not, increase vibration time. If honeycomb on lower surface, move one vibrator lower and tighten seals). 4. Small pinholes in finish (often difficult to determine cause). Usually from: too wet mix; air entering, or other additives; possibly from form oil, or boiling in of air from action of form where form wall is too flimsy and flexes too much, weld on stiffeners to form wall). 5. Larger pinholes – if all over, try reducing water content, vibrating longer after pour, adding additional vibrator, or re-vibration before initial set. BURIAL VAULTS Model VSP-510 Rotary Piston Vibrator used on Burial Vault (page 9). Same wedge brackets and vibrators as on septic tanks can also be used. Wedge brackets give a 90-100% vibration transfer. Pin brackets 60-75%.

3-Step Form using US-900 Electric with UW-2 Wedge Bracket.
Concrete steps are generally poured either upside-down or straight up. Either way, our high frequency Model US-900 or US-1600 is the most frequently used electric vibrator. The SVRW-4000 or CCW-2000 (page 2-3) can be used if air vibrators are desired. They are placed on form stiffeners on the inside transmitting the vibration to the form side. Apply the same general rules for obtaining strong and smooth surfaces as for septic tanks.
Internal vibrators are used on many forms. The general disadvantages are that they tie up one man moving the vibrator around the form. They push air bubbles against the form side where they stick, leaving the surface pitted and unattractive to look at, sometimes leaving the customer believing the product is inferior. The external vibrators, by design, can be left running in the bracket, releasing the operator to do other work until the vibrator is turned off or moved. The vibration travels along the form side pushing the air bubbles away from it, up and out of the mix, leaving a void-free, smooth and attractive surface. For an especially smooth surface, sometimes a minute or so of vibration just before the concrete sets (after vibration) gives excellent results.

PROBLEM: 48” high x 10” square exposed aggregate pillars were impossible to vibrate internally due to the exposed aggregate. Customer was looking for other ways to produce his product. ANSWER: A vibrating table large enough to hold the molds was constructed and two model 4P-1000 electric motor vibrators were used. The forms were moved down to the vibrating table on a roller conveyor put on the table – concrete was added (390 lbs.) and vibrated. Total fill and vibration time appr. 2 minutes. RESULT: Good – 1800 RPM vibrators showed the best results. Higher frequency vibrators were also used but the upper layers of concrete did not get enough vibration. The higher amplitude low frequency 4P-1000 vibrators gave the best result.

LARGE CONCRETE PIPE FORMS
VIBRATORS MOST COMMONLY USED PNEUMATIC: The High Frequency Model SVRL(S)-4000, 5500, 8000 are by far the most popular vibrators for large concrete pipe. These units require the least amount of maintenance, are light and easily portable. The high frequency will place the concrete fast, give excellent surface finish and strength. (See page 6 & 7 for technical data).
ELECTRIC: VIBCO Model 2P-3500 and 2P-5500 totally enclosed units are especially designed for the concrete pipe industry. These units have adjustable force up to 4500 lbs. for 2P-3500, 5500 lbs. for 2P-4500, and 6500 lbs. for 2P-5500. These units have specially treated windings to withstand mechanical failure and Class F High Temperature insulation to withstand considerable overload. These units have two roller bearings for long life. They can be mounted with rotor shaft vertically or horizontally. They are made in the U.S. and follow NEMA & ASTME standards. All parts are available from the factory. (See page 16 and 17 for technical data.)

APPLICATION SUGGESTIONS 1. Vibrators are placed 5’ to 10’ apart on alternate side of form. Spacing depends on height of form and slump of concrete. Start by mounting vibrators 2 to 3’ from the ends, 16 to 24” from bottom.
2. Start vibrators when concrete reaches 6” to 10” above them. Continue vibrating until a flat glistening surface appears on top and no more air bubbles break on surface.
3. The most popular vibrators for the prestressed and precast industries where a large mass of concrete has to be vibrated are the high frequency pneumatic SVR line (p14-15). An alternative in the electric line is the 2P, 3600 rpm, 3-phase units (p16-17).
*Based on 3”-5” slump concrete, steel form, “average” conditions. Other shapes and conditions see “General Guide” on next page.

Rule of thumb for sizing vibrators for bins and hoppers: figure out total weight of material in sloping portion of the bin or hopper and divide weight by 10. This figure is the total force needed on the vibrator or vibrators to be selected. (For more information, see General Catalog or Catalog #9803: Vibrators for Sand and Gravel and Ready Mix Concrete Procedures. Use vibrators with 3600 VPM for course material such as sand, etc. Over 5000 VPM for fine fluffy materials such as cement, etc.
CEMENT WEIGH BATCHER Customer had problem emptying weigh batcher which caused scale inaccuracies, improper mixes and delays in loading. The old fashioned rap-with-a-hammer solution was slow and caused damage to the batcher wall. VIBCO’s Model US-450 115 volt electric vibrator was mounted on the hopper. See pictures and diagrams. Vibrator was plugged into available light outlet and with a switch, operator turns on vibrator when loading a truck and off when dial scale reads zero. (Comparable pneumatic vibrator Model VS-320 silent turbine or Model 55-1-1/2 Piston). Customer now gets reliable mixes and no delivery or loading delays.
SAND BIN Customer had problem with wet sand sticking to bin sides. A Model 2P-800 electric vibrator was mounted to bin side. See photo and mounting diagram. Sand now moves freely - customer has no further problems.
